Multidimensional Assessment of Functional Outcomes in Schizophrenia: Results From QUALIFY, a Head-to-Head Trial of Aripiprazole Once-Monthly and Paliperidone Palmitate.

ABSTRACT: QUALIFY was a 28-week, randomized, open-label, head-to-head trial that assessed improvements across multiple measures in stable patients with schizophrenia with aripiprazole once-monthly 400 mg vs paliperidone palmitate.Secondary effectiveness assessments included physician-rated readiness for work using the Work Readiness Questionnaire, the Clinical Global Impression-Severity and Clinical Global Impression-Improvement scales, and quality of life with the rater-blinded Heinrichs-Carpenter Quality of Life Scale. Patients assessed their treatment satisfaction and quality of life with Subjective Well-Being under Neuroleptic Treatment-short version and Tolerability and Quality of Life questionnaires.Odds of being ready for work at week 28 were significantly higher with aripiprazole once-monthly 400 mg vs paliperidone palmitate (adjusted odds ratio, 2.67; 95% CI, 1.39-5.14; P=.003). Aripiprazole once-monthly 400 mg produced numerically or significantly greater improvements from baseline vs paliperidone palmitate in all Quality of Life Scale items. With aripiprazole once-monthly 400 mg vs paliperidone palmitate at week 28, there were significantly more Clinical Global Impression-Severity and Clinical Global Impression-Improvement responders (adjusted odds ratio, 2.26; P=.010, and 2.51; P=.0032) and significantly better Clinical Global Impression-Improvement scores (least squares mean treatment difference, -0.326; 95% CI, -0.60 to -0.05; P=.020). Numerically larger improvements with aripiprazole once-monthly 400 mg vs paliperidone palmitate were observed for patient-rated scales Subjective Well-Being under Neuroleptic Treatment-short version and Tolerability and Quality of Life. Partial correlations were strongest among clinician-rated and among patient-rated scales but poorest between clinician and patient-rated scales.Consistently greater improvements were observed with aripiprazole once-monthly 400 mg vs paliperidone palmitate across all measures. Partial correlations between scales demonstrate the multidimensionality of various measures of improvement. More patients on aripiprazole once-monthly 400 mg were deemed ready to work by the study end.National Institutes of Health registry, NCT01795547, https://clinicaltrials.gov/ct2/results?id=NCT01795547).

Project description:BACKGROUND:A post hoc analysis from a multiphase trial with open-label transition and maintenance phases, a double-blind relapse prevention phase, and an optional open-label extension examined the long-term tolerability with continuous once-monthly injectable paliperidone palmitate 39, 78, 117, or 156 mg (25, 50, 75, or 100 mg equivalents [mg eq] of paliperidone) in subjects with recently diagnosed (?5 years; n = 216) versus chronic illness (>5 years; n = 429) schizophrenia. METHODS:Adverse events reported at a ?2% margin between subgroups were identified. Relative risks (in the recently diagnosed compared with the chronically ill) and 95% confidence intervals (CI) were determined, and CI not including 1 were considered potentially significant. RESULTS:In both subgroups, the mean monthly dose was 109 mg (69.9 mg eq). Continuous mean exposures were 333.9 ± 271.9 and 308.7 ± 278.3 days in the recently diagnosed and chronic illness subgroups, respectively. Using the criteria outlined in the methods, nasopharyngitis was a potentially significant event reported in more chronically ill than recently diagnosed subjects at months 6, 9, 12, and endpoint (7.2% versus 2.8%; relative risk 0.384; 95% CI 0.163-0.907). Influenza (2.8% versus 0.7%; relative risk 3.9; 95% CI 1.003-15.730) and amenorrhea (3.2% versus 0.9%; relative risk 3.476; 95% CI 1.029-11.744) at endpoint were potentially significant events in more recently diagnosed than chronically ill subjects. Mean weight changes, sedation/somnolence, any extrapyramidal symptom-related or glucose-related events were generally similar between the groups. The mean prolactin level increased in both sexes in both subgroups (changes from baseline of +41.8 ng/mL and +26.5 ng/mL in recently diagnosed and chronic illness females and +12.3 ng/mL and +15.1 ng/mL in recently diagnosed and chronic illness males, respectively), and were higher in females with recently diagnosed illness than in females who were chronically ill (P = 0.0002 at endpoint). Prolactin-related events were reported by 7.9% of recently diagnosed subjects with schizophrenia and 3.5% of those who were chronically ill. CONCLUSION:The long-term tolerability of paliperidone palmitate was generally similar in recently diagnosed schizophrenia subjects and those with more chronic illness, with the exception of some prolactin-related measures.

Project description:PURPOSE:Reducing the dosing frequency of antipsychotics (APs) with long-acting injectables (LAIs) such as once-monthly paliperidone palmitate (PP1M) can improve adherence and clinical outcomes for schizophrenia patients. This US study compared physical and psychiatric comorbidity-related outcomes, AP adherence, healthcare resource utilization (HRU), and costs pre- and post-transition to PP1M among schizophrenia patients treated with oral risperidone/paliperidone pre-PP1M transition. METHODS:Health insurance claims from the IQVIA™ PharMetrics Plus database (01/01/2012-07/31/2018) were used to identify adults with???2 schizophrenia diagnoses,???1 claim for PP1M, and???30 days of treatment with oral risperidone/paliperidone in the 60 days before the first PP1M claim (i.e., the index date). Comorbidity-related outcomes, adherence to APs (measured via the proportion of days covered [PDC]), all-cause per-patient-per-month (PPPM) HRU, and all-cause PPPM medical, pharmacy, and total costs (i.e., sum of medical and pharmacy costs) during the 6-month periods pre- and post-transition to PP1M were compared using generalized estimating equation models adjusted for repeated measurements. Analyses were replicated in the subset of patients with???1 all-cause inpatient stay pre-PP1M transition. FINDINGS:Among 427 schizophrenia patients transitioning from oral risperidone/paliperidone to PP1M, the mean age was 41.1 years and 37.9% were female. Following the PP1M transition, patients were less likely to have claims with a diagnosis for psychoses (odds ratio [OR] 0.41; P?<?0.001), hypertension (OR 0.80; P?=?0.011), depression (OR 0.70; P?<?0.001), drug abuse (OR 0.60; P?<?0.001), substance-related and addictive disorders (OR 0.73; P?=?0.003), bipolar and related disorders (OR 0.59; P?<?0.001), sleep-wake disorders (OR 0.68; P?=?0.017), anxiety disorders (OR 0.78; P?=?0.034), and other conditions that may require a focus of clinical attention (OR 0.58; P?<?0.001). Mean PDC by APs was higher post-PP1M (mean?=?0.81) versus pre-PP1M (mean?=?0.68) transition. Post-PP1M, patients were less likely to have an all-cause emergency room visit (OR 0.51; P?<?0.001) or inpatient stay (OR 0.39; P?<?0.001) compared to pre-PP1M. All-cause total healthcare costs remained similar post- versus pre-transition to PP1M (mean monthly cost difference [MMCD]?=?$228; P?=?0.260). Pharmacy costs increased post-PP1M (MMCD?=?$960; P?<?0.001), but were offset by decreasing medical costs (MMCD?=?- $732; P?<?0.001), largely driven by lower costs related to inpatient stays (MMCD?=?- $695; P?<?0.001) and emergency room visits (MMCD?=?- $63; P?<?0.001). For patients with???1 all-cause inpatient stay pre-PP1M transition (N?=?177), a more pronounced improvement in comorbidity-related outcomes, a more pronounced reduction in HRU, and a reduction in total healthcare costs (MMCD?=?- $1308; P?<?0.001) were observed post-transition to PP1M. IMPLICATIONS:Among schizophrenia patients in the US, transitioning to PP1M following oral risperidone/paliperidone treatment was associated with improved comorbidity-related outcomes, higher adherence, and a reduction in HRU, while remaining cost neutral. Furthermore, patients with???1 all-cause inpatient stay pre-PP1M transition had significantly lower total healthcare costs post-PP1M transition.

Project description:BACKGROUND:The negative symptoms of schizophrenia are generally harder to recognize, more difficult to treat than positive symptoms, and have a significant impact on patient functioning and overall outcomes. Treatment with aripiprazole may be associated with benefits on negative symptoms and functioning given its partial agonism to the dopamine D2 receptor. The aim of this subanalysis was to explore the impact of flexibly dosed, long-acting paliperidone palmitate once monthly (PP1M) on negative and depressive symptoms, disorganized thoughts, anxiety, extrapyramidal symptoms, and patient functioning in nonacute adult patients with schizophrenia previously unsuccessfully treated with oral aripiprazole monotherapy. METHODS:Post-hoc subanalysis of 46 nonacute but symptomatic patients enrolled in a prospective, interventional, single-arm, multicenter, open-label 6-month study. RESULTS:At endpoint, improvements of ? 20% and ? 50% in the Positive and Negative Syndrome Scale (PANSS) total score were observed in 52.2% and 21.7% of patients, respectively. Significant and clinically relevant improvements were observed at endpoint in mean (standard deviation [SD]) PANSS negative subscale score (-3.0 (5.0); p < 0.0001) and in the PANSS Marder factor scores for negative symptoms (-2.9 (5.4); p = 0.0006), disorganized thoughts (-2.8 (4.3); p < 0.0001) and anxiety/depression (-1.8 (3.9); p = 0.0031). Patient functioning assessed by mean (SD) Personal and Social Performance scale score (3.9 (13.2); p = 0.0409), Mini International Classification of Functioning rating for Activity and Participation Disorders in Psychological Illnesses total scores (-2.9 (7.1); p = 0.0079), and Extrapyramidal Symptom Rating Scale scores (-0.6 (3.4); p = 0.0456) improved significantly at endpoint. PP1M was well tolerated with no new safety signals. CONCLUSIONS:Six-month treatment with flexibly dosed PP1M was associated with significant and clinically relevant improvements in negative and depressive symptoms, disorganized thoughts, functioning, and extrapyramidal symptoms in nonacute but symptomatic patients with schizophrenia previously unsuccessfully treated with oral aripiprazole.
